Not absolutely certain it's right to do this, but since there's
no error value coming back, it seems reasonable.

After a prefix match, the old code advanced the length of the
prefix. This is incorrect since the full match might begin
in the middle of the prefix. (Consider "aaaab+" matching
"aaaaaab").

The bug was that for an anchored pattern such as ^x, the prefix
scan ignored the anchor, and could scan the whole file if there was
no x present. The fix is to do prefix matching after the anchor;
the cost miniscule; the speedups huge.

#pragma dynexport is no longer needed for
this use of cgo, since the gcc and gc code are
now linked together into the same binary.
It may still be necessary later.
On the Mac, you cannot use the GOT to resolve
symbols that exist in the current binary, so 6l and 8l
translate the GOT-loading mov instructions into lea
instructions.
On ELF systems, we could use the GOT for those
symbols, but for consistency 6l and 8l apply the
same translation.
The translation is sketchy in the extreme
(depending on the relocation being in a mov
instruction) but it verifies that the instruction
is a mov before rewriting it to lea.
Also makes typedefs global across files.

This is largely based on ality's CL 2747042.
crypto/rc4: API break in order to conform to crypto/cipher's
Stream interface
cipher/cipher: promote to the default build
Since CBC differs between TLS 1.0 and 1.1, we downgrade and
support only 1.0 at the current time. 1.0 is what most of the
world uses.
Given this CL, it would be trival to add support for AES 256,
SHA 256 etc, but I haven't in order to keep the change smaller.

This Flush is equivalent to zlib's Z_SYNC_FLUSH.
The addition of the explicit Writer type opens the
door to adding a PartialFlush if needed for SSH
and maybe even FullFlush. It also opens the door
for a SetDictionary method to be added.

The code used interfaces in a pretty, pedagogical way but not efficiently.
Remove unnecessary interface code for significant speedups.
Before:
regexp.BenchmarkLiteral 1000000 2629 ns/op
regexp.BenchmarkNotLiteral 100000 18131 ns/op
regexp.BenchmarkMatchClass 100000 26647 ns/op
regexp.BenchmarkMatchClass_InRange 100000 27092 ns/op
regexp.BenchmarkReplaceAll 100000 27014 ns/op
After:
regexp.BenchmarkLiteral 1000000 2077 ns/op
regexp.BenchmarkNotLiteral 100000 13738 ns/op
regexp.BenchmarkMatchClass 100000 20418 ns/op
regexp.BenchmarkMatchClass_InRange 100000 20999 ns/op

There's likely more to do without major surgery, but this is a simple, significant step.

- change Walk signature to use an ast.Node instead of interface{}
- add Pos functions to a couple of ast types to make them proper nodes
- explicit nil checks where a node can be nil; incorrect ASTs cause Walk to crash
For now ast.Walk is exercised extensively as part of godoc's indexer;
so we have some confidence in its correctness. But this needs a test,
eventually.
